The present invention refers to a loopknitting tenni (or. 66-117) device, particularly suitable for picking-up run or fallenloops, being of the type which comprises a locking member hinged to said needle parallel to its normal axis, which in one of the end positions of the needle engages with the point of the needle, forming a loop between the needle and This type of needle is commonly used in" the above mentioned work, and in said'devicef the lock ng members acts asa thread selector, being operatedlby the proper threadsof the loop, in

' 'both the rising and-the "descending strokes of the needle is mounted on mean which perform the opening of the loop by causingthe rotation or swinging, of the locking member during the descending stroke of the needle and thus serve as a guide for said locking member during its rotation in the reverse direction. thereby preventing the same from engaging with the surface of the loop.

Another characteristic of the invention consists in that the said means for operating and guiding the locking member are maintained in contact with the same until the moment of 010- sure of the loop, and will only separate therefrom after said closure. for allowing the passage of the loop thread which was supported on the back of the locking member. so that the said thread cannot escape from the locking member before the closure of the loop and thus allow said thread to enter into the loop.

The slide 2 i provided with a plurality of orific'es I! for the purpose of reducing the weight of the device.

Supposing now the device to be in the position shown in Figure l, the slide 2 bears with its lower face on the threads which are to form the loop, and the needle 8, in consequence, passes between two of said threads. The locking member U will closely apply its end against the needle 8, so'thatv between the twoparts a small notch will be formed, adapted to engage, at one time, with a single thread during the rising stroke of the needle 8, so as to draw said thread through the opening 3 of the slide 2. The said thread will exert a strong traction on the locking member ii and thereby oblige the same to rest on the upper face of thesmall blade 6, while closing the same on the hook III, which latter, when passing between the threads of the loop, will engage with Other details of the invention will be appreciated in the course of the following description of preferred embodiment. of the same, illustrated by way of example in the accompanying drawing, in which:

As soon as the hook ill passes beyond the orifice 3, which it will do snugly applied against the plate 6, the locking member I i will contact with said hook l0 and thus allow the thread which was held on the locking member H, to pas to the lower part of the slide 2.

Mean- WhiIQythe needle 8 will have descended behind the first of said threads and will thus have been interlocked by the second of the said threads, whereupon the device will return to its initial nntr eqm tezre e heieoe et vae c e tion is given 105% way of illustrative example only,
